Evaluation
Of Microbiological Quality And Aflatoxin Mi (AFM1)
Contamination Of Milk Powder Samples
Sold In Nigeria Market

Abstract:
Milk, a natural liquid food, is
one of the most nutritionally complete foods, adding
high-quality protein, fat, milk sugar, essential minerals, and
vitamins to diet. Milk
could also be a source of contaminants such as microorganisms
and aflatoxin M1 (AFM1).
Aflatoxins are important
toxins whose consumption could cause food borne diseases. The
microbiological quality and Aflatoxin M1 (AFM1)
contamination of twenty five milk powder samples (10 brands)
imported, branded and sold in Nigerian market were evaluated.
The total heterotrophic, coliform, Bacilli counts ranged from
2.0 - 8.2 x101cfu/g, 1.0 - 4.0cfu/g and 3.0 – 4.1 x
101cfu/g respectively. There was no detection of
Salmonella/ Shigella, Vibrio, lactic acid bacteria,
Staphylococcus and E. coli, Yeast and mould in any
samples. The bacteria isolates found in the samples were
Bacillus subtilis, B. lincheniformis, B. cereus, Proteus
mirabilis and Proteus vulgaris among which B.
subtilis had the highest frequency of occurrence (48.8%).
Fungi were also not detected in the samples. The microbial loads
of the milk samples were found to be lower than the specified
standard limits (102 - 103 cfu/g for
bacteria) as recommended by United State Food and Drug
Administration (USFDA). The AFM1 level ranged between
0.13±0.01y – 3.75±0.01a ppb (n = 25) and
was found in all the samples tested. In approximately 80% of the
samples, level of contamination was above the permissible
concentration (0.5ppb) as specified by European Union (EU).
About 20% contain AFM1 at level below tolerance limit
specified by FDA. There were significant differences (P≥0.05) in
the mean values of AFM1 in the samples from the same
brand. The detection of AFM1 in the milk powder
samples could be of public health significance and hence there
is an urgent need for concerned regulatory bodies to impose
necessary measures to safeguard health of consumers. In
conclusion, while the microbial load of milk powder samples did
not pose public health problem, the level of AFM1
contamination called for serious attention in the country.

Abstract:
In the earlier days of
distance learning, it was most common to see distance learning
used for rural students who were at a distance from an
educational institution. The student might watch a telecourse on
a television stations, read texts, mail in assignments and then
travel to the local college to take an exam. This model is still
in use, but as the technology has become more sophisticated and
the cost of distance learning dropped as equipment prices
dropped, the use of distance education has increased. High
front-end costs prevented an early widespread adoption of
electronically mediated learning. Distance learning has been
aggressively adopted in many areas because it can meet specific
educational needs. As the concept of accountability became
accepted and laws required certain courses in high school in
order for students to be admitted to state colleges,
telecommunications was examined as a way to provide student
access to the required courses. Many rural school districts
could not afford the special teachers to conduct required
courses. Distance education met this need by providing courses
in schools where teachers were not available or were too costly
to provide for a few students. It also fulfilled a need for
teacher training and staff development in locations where
experts and resources were difficult to obtain. These systems
link learner communities with each other and bring a wide array
of experts and information to the classroom.

Abstract:
Adult education also does not have a clear definition. In
Chapter One of "The Foundations of Adult Education in Canada",
the author quotes Malcolm Knowles. Knowles states that the term
Adult Education refers to at least three different phenomena.
"...To a set of activities...to the intellectual process by
means of which adults seek, or are assisted, to learn
things...[and] to the social system which is made up of
individuals and organizations concerned with the education of
adults." Adult illiteracy severely hinders the life chances of
young children, undermines school reform, and limits the
opportunities for postsecondary education.
The field of adult education and literacy is plagued by
confusion about definitions. Over the years definitions have
evolved from provisions in federal law and initiatives of groups
advocating particular methodologies or the needs of specific
adult populations. The result is that definitions tend to merge
statements about the goals to be achieved (e.g., improving the
literacy of a particular population) with a particular means
(e.g., adult basic education) to achieve the goal.

Abstract:
The development of the intensive agriculture in our country
between 1960 and 1990 totally over passed the aspect connected
with the negative impact of the toxic chemical compounds on the
air, water and soil. Using chemical products as nutrients,
fertilizers and pesticides,
we believe that we attack our safety and we must know the
effects of pesticides from these compounds.
Application of pesticides in the paddy fields has deleterious
effects on non-target organisms including Azolla which are
photosynthesizing and nitrogen fixing micro-organisms
contributing significantly towards soil fertility and crop
yield. Pesticide contamination in the paddy fields has
manifested into a serious global environmental concern. Present
study was aimed to study the comparative effect of two such
pesticides, a well-known species of Azolla, Azolla Microphylla
were selected for their stress responses to an Organochlorine
insecticide - Endosulfan, and Organophosphate insecticide-Monocrotophos
with reference to their growth, Free radicals, Antioxidant
enzymes and metabolites. Azolla microphylla strains were
adversely affected by the insecticide doses and inhibition was
dose dependent. But the highest decrease was seen in case of
organochlorine insecticides.
Pesticide treatment with increasing doses accelerated the
formation of reactive oxygen species progressively, whereby an
enhanced Antioxidant enzymes and metabolites were noticed in A.
microphylla.
On the other hand, increased amount of proline in all the
insecticide treated concentrations was indicative of stressed
activities of the organisms.
In this work the effect of the insecticides on Azolla
microphylla resulted in growth inhibition, a decline of
physiological and biochemical activities
but the highest effect was shown in case of organochlorine
insecticide which is commonly used in the rice fields.

Abstract:
The present study has
been carried on causes of dropouts in education zone Khag
District Budgam. (1) Most of the schools are not accessible to
people. The national policy on education and right to education
had guaranteed education for all which seems far reality in this
Zone. (2) Most of the schools have very less teacher student
ratio, which has a direct impact on the performance of these
schools. Moreover, the extracurricular activities are altogether
lacking in these schools. (3) The study showed the total dropout
of students from year 2010 to 2011 in two classes i.e. 6th
and 7th as 61. (4) There has been very less
enrollment of girls in the Schools and among girls the dropout
has been high in lower classes while as the dropout among boys
is higher in higher classes. (5) The Middle School Hamchipora
has the highest percentage of dropouts from the class 7th
to 8th in year 2010–2011. (6) Most of the dropouts
were found engaged with the traditional occupation of cattle
grazing in high altitude areas as cattle grazing are their
traditional and one of the major livelihood options. (7) Some of
the areas which are at high altitude, in most of the other areas
dropouts were found to be engaged with agricultural practices.
(8) It was found that many dropouts were “job card holders”
under MGNREGA.

Abstract:
The present study focused on the Assessment of
Environmental Knowledge, Awareness and Practices of college
students in Government Sheikhul Alam Degree College Budgam, J&K.
Television and radio are conservation out of their interests and
hobbies in watching television and listening to radio. Other
sources in information are newspapers, textbooks and magazines
which shows the availability of these reading materials in the
school. Teachers do not integrate well environmental issues,
concepts and protection and conservation practices in their
daily lessons or throughout the teaching-learning process.
Likewise, their parents and friends are not those
environmentally-oriented citizens to share them the knowledge of
protecting and conserving the environment. The students are too
much exposed to information technology like internet. In the
performance of students in the achievement test only two among
120 students are excellent who got the highest scores, most of
them performed poor, and some performed very poor.

Adult Learning in
agricultural education

Former Graduate Student (M. S), science and research branch,
Islamic Azad University, Tehran, Iran
E-mail:
amirhosseinpirmoradi@yahoo.com
Abstract:
Your assessment process should be transparent and allow for
ongoing feedback from and to the learners. Remember these adult
learners want to improve their skills in managing money and are
not necessarily interested in formal recognition or being ranked
against their peers in the group. Where possible, presenters
should emphasize from the start that no-one is going to ‘fail’
the program. Even where students are seeking formal
certification of their achievement, presenters can advise that
there is no competition between the learners in the group or
between an individual and the topic material – it’s all
achievable and everyone can make it work for them. Your program
should employ methodologies so that your trainers establish a
friendly, open atmosphere that shows the participants they will
help them learn rather than present as ‘experts’ imparting
knowledge. No-one engages well with a trainer/teacher who is
just ‘showing off’ what they know. Financial services have a
plethora of jargon and complicated ideas that can put many lay
people off. Exposing this sort of terminology and explaining it
in simple terms – or deciding whether some of it needs exposure
at all – is paramount to keeping your learner’s trust and
interest.

Abstract:
However rural women play major role to produce food at all over
the world, but rarely enjoy of extension services. Wherever,
rural women as producers of food productions and family
supervisor, have little contact with extension services
organizations, so their problems and needs would reflect at
extensional information feedback, rarely. Therefore agricultural
research institutions wouldn’t be able to create and develop
technology, suitable for their needs. Global surveys show that
about 5% of total extension resources, at all over the world
dedicated to programs for female farmers, but women form just
15% of extension personnel of world. Some extensional issues
that traditionally belong to women, such as economy of family,
are supported very little that receive just about 1% of total
extension resources of agriculture.

Abstract:
Spent mushroom
compost (SMC) of Pleurotus ostreatus (an edible fungus)
was used as soil conditioner for the improvement of growth of a
leguminous agricultural crop (Soya bean (Glycine max).
The experiment was conducted in a screen house, located behind
the Department of Botany and Microbiology, University of Ibadan.
The experiment was laid out in a Complete Randomized Design and
Replicated with six(6) treatments; 0%,10%,20%,30%,50% and 100%
Results from this investigation shows that this dicot, soybean
performed well at 10% (0.6kgSMS/6kg soil) treated level on most
of its agronomic characters and yield (pod no, FW and DW)
parameter. It was observed that, there were seed production on
the control experiment plants, but were significantly lesser
with the SMC treated seeds/plants(p≤0.05),. However the control
(soil) and Ref. Control (SMS only) produced less fruit (Pod) .
It was also found that the substrate pH for growing these crops
at all treatment level was increased from acidity to
neutrality. The results from these findings were discussed in
relation to the usage of SMC as a possible organic fertilizer
for the improvement of this leguminous crop.

Abstract:
This study reports on
the microbiological analysis of ready to eat food (cooked rice
and beans) sold in University of Port Harcourt, Port Harcourt,
Nigeria. The total colony count of ready to eat (cooked rice)
ranged from 2.45x105cfu/g to 17.8x105cfu/g
and 3.5x104cfu/g to 17.1x104cfu/g for
ready to eat beans samples, for bacterial. The data’s revealed
that bacteria isolated from both food samples collected from the
restaurants in University of Port Harcourt are Bacillus
cereus, Staphylococcus aureus, Escherichia coli, and
Klebsiella pneumoniae which is mainly associated with food
poisoning because of its ability to produce toxins. From the
result gotten, it was indicated that these ready to eat food
samples that were analyzed, did not meet the bacteriological
quality standard. The presence of pathogenic bacteria in
ready-to-eat foods should receive particular attention, because
their presence indicates public health hazard and give warning
signal for the possible occurrence of food borne intoxication.
More closely supervision should be made on these restaurants
around the university of Port Harcourt community by relevant
authorities, and more analysis should be carried out on other
food samples sold in the University of Port Harcourt community,
to ensure proper food quality standard.

Abstract:
This study investigated the prevalence and the causative
organisms of asymptomatic bacteriuria among pregnant women
attending their first prenatal visit at University of Port
Harcourt Teaching Hospital (UPTH) and Braithwaite Memorial
Hospital (BMH), both in Port Harcourt, South Southern Nigeria. A
retrospective analysis was performed on the routine prenatal
screening (urine culture tests) of 9,698 women attending their
first prenatal clinic visit between 1 January 2011 to 31 July
2012. They were reviewed, analyzed, and correlated with data on
patients’ age, nationality, gravidity, and number of previous
abortions. Of 9,698 women, only 166 (1.7%) showed significant
bacterial growth, and 1,918 patients (19.8%) were reported as
heavy mixed growth. The most common bacterium isolated was
Escherichia coli on 88 patients (53%). In this study, low
prevalence of bacteriuria among pregnant women was compared to
published studies conducted in other countries. In view of the
paucity of information regarding asymptomatic bacteriuria in
pregnancy, and the findings of this study, there is need to
conduct a nation-wide survey to guide the revision of medical
practice on a national scale in Nigeria.

Abstract:
While there is still prejudice
surrounding some distance learning, it is increasingly being
accepted as an alternative to traditional classroom learning.
Courses can be offered via the Internet, where students are able
to interact with instructors and other students without
physically being in the same room. Getting a college education
can be difficult for people with inflammatory bowel disease (IBD).
Frequent trips to the restroom, exhaustion, doctor visits, and
medication side effects are all barriers to the traditional
college experience. What if you could get the degree without
ever setting foot on a campus? You can do just that through
distance or virtual learning. Distance learning has been around
for a long time (we've all seen the commercials on TV).
